Homework 13: Implementing Priority Queues

Assigned: Tuesday, March 14, 2006
Due: 8:00 a.m., Wednesday, March 15, 2006

Summary: In this assignment, you will consider how to implement priority queues.

Purposes: To help you think about implementing ADTs.

Contents:

The Assignment

A priority queue is a linear structure in which the get operation removes the smallest value in the structure.

You now know a variety of techniques for implementing collection ADTs, including placing the values in an array, placing the values in a group of linked nodes, and variations on the two.

In English (with approximate code, as necessary), suggest how you might implement priority queues. That is, you should describe the underlying representation as well as the implementations of the put and get methods.
